i18n Compliance for Regulated Industries: FDA, GDPR, GxP & SAP Requirements

We almost failed an FDA audit because of our translation workflow

Three years ago, I was leading the localization effort for a medical device companion app. We had 47 languages, 12,000 translation keys, and what I thought was a solid process. Then the FDA auditor asked a question that made my stomach drop:

"Can you show me who approved the Japanese warning labels, when they were approved, and what the original English text was at that time?"

We couldn't. Not completely. Our translation files were in git, sure, but linking a specific translation to its approval workflow, the translator who verified it, and the exact source text version? That took us three days of forensic git archaeology to piece together.

We passed the audit, barely. But that experience changed how I think about translation management in regulated environments. If you're building software for healthcare, life sciences, financial services, or any industry where auditors show up, this post is for me three years ago.

The regulatory landscape nobody prepares you for

Most i18n tutorials assume you're building a consumer app where a slightly off translation is just embarrassing. In regulated industries, a mistranslation can mean:

The stakes are different. Your translation management system isn't just a developer convenience—it's a compliance control.

FDA 21 CFR Part 11: The gold standard for validation

If you're in life sciences, you've heard of 21 CFR Part 11. It's the FDA regulation governing electronic records and signatures. What most teams don't realize is that it applies to your translation system too.

The key requirements that affect localization

Electronic signatures: When a translator or reviewer approves a translation, that approval must be tied to a unique user identity. No shared accounts. No anonymous approvals.

Audit trails: Every change to a translation must be logged with:

System validation: Your TMS needs documented evidence that it works as intended. This means validation protocols, test scripts, and traceability matrices.

Record retention: You need to keep translation records for the lifetime of the product plus additional years depending on the product type. For some medical devices, that's 20+ years.

What this looks like in practice

When we rebuilt our translation workflow post-audit, we ended up with something like this:

The tricky part? Most translation management systems weren't built with this in mind. We ended up having to layer compliance controls on top of our existing tools.

GDPR language requirements: It's not just about consent forms

Everyone knows GDPR requires privacy notices in local languages. But the language requirements go deeper than most realize.

The rights that require language support

Right to access (Article 15): Users can request all their data. That response needs to be in a language they understand. If your system only stores data labels in English, you have a problem.

Right to be informed (Articles 13-14): Privacy notices must be in clear, plain language. "Plain language" is interpreted as the user's native language in most EU member state implementations.

Right to rectification (Article 16): Users correcting their data need to understand the interface. A German user shouldn't have to navigate an English-only data correction flow.

The translation quality bar is higher

For GDPR compliance, "machine translation reviewed by a native speaker" often isn't sufficient. Data protection authorities have specifically called out:

We've seen companies get dinged not for missing translations, but for translations that were technically correct but created ambiguity about consent scope.

Practical implications

If you're building anything with EU users, your translation workflow needs:

GxP compliance: Pharma's validation framework

GxP is the umbrella term for Good Practice regulations in the pharmaceutical industry. GMP (Manufacturing), GLP (Laboratory), GCP (Clinical), GDP (Distribution)—they all have implications for localization.

Why translation is a GxP concern

In pharmaceutical contexts, translations appear in:

A mistranslation in any of these can affect patient safety. That's why regulatory bodies treat translation as a quality-critical process.

The documentation burden

GxP validation requires you to document:

User Requirements Specification (URS): What does your translation system need to do? This isn't just features—it's compliance-relevant capabilities.

Functional Specification: How does the system implement those requirements?

Validation Protocol: How will you test that the system works correctly?

Validation Summary Report: Evidence that testing was completed and passed.

For a translation management system, this might mean testing:

The real cost of GxP-compliant translation

Here's something vendors don't tell you: GxP validation is expensive. We've seen companies spend $50K-$200K just validating their TMS, depending on the system complexity and documentation requirements.

This is why many regulated companies either:

The industry needs better options here. A TMS that's designed for regulated environments from the start would save everyone a lot of pain.

SAP localization: The enterprise reality

If your company runs SAP, localization has another layer of complexity. SAP systems generate user-facing text through transaction codes, custom programs, and dozens of configuration points.

SAP-specific translation requirements

Text elements: Custom ABAP programs have text elements that need translation. These follow SAP's SE63 transaction code workflow.

Data elements: Field labels and documentation come from data dictionary entries.

Messages: System messages are stored in message classes with language variants.

Smart Forms and SAPscript: Print documents and correspondence have their own translation mechanisms.

Integration challenges

Most external TMS platforms don't integrate well with SAP. You end up with:

Some companies just use SAP's built-in translation tools (SE63, transaction SLXT) for everything SAP-related and a separate TMS for web/mobile. It's not elegant, but it avoids the integration nightmare.

Transport management for translations

SAP translations live in transport requests. This means:

I've seen SAP translation projects fail not because of translation quality, but because the transport strategy wasn't planned.

Building a compliance-ready translation workflow

After going through audits, remediations, and rebuilds, here's the workflow I'd recommend for regulated environments:

1. Centralized source of truth

All translations must live in one system that:

Spreadsheets and git repos alone don't cut it. You need a system designed for traceability.

2. Approval workflows that match your quality requirements

Not all translations need the same level of review:

Configure your TMS to enforce these workflows automatically.

3. Version control with context

When regulators ask "what did the user see on March 15, 2024?", you need to answer that definitively. This requires:

4. Integration with your quality management system

Your translation process should connect to your broader quality system:

5. Validation documentation

Before going live, prepare:

Keep this documentation updated as the system changes.

AI translation in regulated environments: The elephant in the room

Here's where it gets interesting. AI translation is transforming localization, but regulated industries are approaching it cautiously.

Current regulatory stance

FDA: No explicit prohibition on AI translation, but the output must meet the same quality and traceability standards as human translation. You need to validate the AI translation process and have human review for critical content.

EU MDR (Medical Device Regulation): Requires translations to be accurate and verified by qualified persons. The mechanism (AI vs. human) isn't specified, but the verification requirement effectively mandates human review.

EMA (European Medicines Agency): Recommends human translation for patient-facing content. AI may be acceptable for internal documents with appropriate review.

Practical approach

Most regulated companies we work with use AI as a first-pass translation with mandatory human review. The workflow looks like:

This gives you the speed benefits of AI while maintaining the human oversight that regulators expect.

The key is traceability. Your system needs to record:

Real-world implementation timeline

Based on our experience, here's a realistic timeline for implementing a compliant translation system:

Total: 6-12 months for a full implementation. Yes, it's a long time. But cutting corners here creates audit findings later.

The bottom line

Translation compliance in regulated industries isn't optional, and it isn't simple. But it's also not impossible. The key is treating your translation workflow as a quality-critical process from the start, not an afterthought to be "fixed" before an audit.

If you're building for healthcare, life sciences, financial services, or any regulated environment:

Your future auditors will thank you. And you'll sleep better knowing that when they ask "who approved this translation?", you have the answer.
